Sensor: The attributes describing the physical device and it’s location
sensor_calibration***: One time settings parameter: The parameters that instruct LiteFarm on how to parse data read by the sensor but don’t change from reading to reading and also aren’t related to the physical nature of the sensor. May just be part of the sensor table!
sensor_reading: Readings from the sensor.
Sensor | ID | Name | Lat_long | Type | Depths | Elevation | … |
|---|---|---|---|---|---|---|---|
Description | The sensor’s unique id. | How the sensor will be labelled in LiteFarm. | The latitude and longitude for the sensor, comma separated. | Valid values to begin are: | Assumed to be in cm, comma delimited if multiple depths. | The elevation of ground level at the location where the sensor is mounted. | |

Description | A unique identifier for this reading. May have some meaning or traceability for Ensemble. | The timestamp when this reading was captured. | The timestamp when this reading was transmitted. | The sensor reporting the reading. | The calibration which instructs on how to interpret the value. Required since each sensor can have multiple types of readings, e.g. “Temperature” and “Moisture”. | The numerical value of the reading. |
